Self-adaptive skin rolling supporting structure

Abstract

The invention provides a self-adaptive skin rolling supporting structure and aims at solving the problem that skin of a skin riveting supporting shaft structure cannot horizontally move smoothly due to the fact that a bearing can be possibly jammed and a supporting shaft cannot roll along with horizontal moving of the skin in the prior art. The self-adaptive skin rolling supporting structure comprises a supporting shaft, a left supporting component and a right supporting component, and the left supporting component and the right supporting component are mounted at two ends of the supporting shaft respectively. The self-adaptive skin rolling supporting structure has the advantages that height difference H of two axial ends of the supporting shaft can be adjusted conveniently to meet requirements on thickness difference of the skin in the width direction, the upper surface of the supporting shaft is ensured to be a horizontal plane after the skin is placed on the supporting shaft, and the supporting shaft is ensured to be capable of smoothly rolling along with horizontal moving of the skin, and the self-adaptive skin rolling supporting structure is simple in structure and low in cost.

Description

technical field [0001] The invention relates to an aircraft skin automatic riveting assembly technology, in particular to an adaptive skin rolling support structure. Background technique [0002] With the rapid development of China's aviation manufacturing industry, it has become an inevitable trend for aircraft skin automatic riveting assembly technology to replace traditional manual riveting assembly technology. In the automatic riveting assembly process of aircraft flat skin, the skin first needs to be clamped on the skin fixture, and then the riveting assembly is performed at the specific position of the skin. During this process, the skin needs to be leveled under the drive of the fixture. move. However, due to the poor rigidity of the skin itself, the skin deforms under the action of gravity, and the place with the largest disturbance in the middle deforms the most, which seriously affects the riveting quality of the skin. To solve this problem, support shafts are us...
